2. Many of the modifications or changes are reasonably necessary because of the
following geological reasons.
(a) The region is located in an area of high seismic activities as indicated by
United States Geological Survey and California Division of Mines and
Geology. Recent earthquake activities have indicated the lack of adequate
design and detailing as a contributing factor to damages that reduced the
protection of the life-safety of building occupants. This reason is
hereinafter referred to as "Geological I."
(b) The region is located in an area of high seismic activities as indicated by
United States Geological Survey and California Division of Mines and
Geology. Recent earthquake activities have indicated the lack of
flexibility of materials and/or building systems has been a contributing
factor to damages that reduced the protection of the life-safety of building
occupants and increased the cost of rehabilitation of structures. This
reason is hereinafter referred to as "Geological II."
3. Many of the modifications or changes are reasonably necessary because of the
following Topographical conditions.
(a) Portions of the City are in hillside areas that are hazardous frre areas that
have only limited fire suppression forces and facilities available for the
protection of life and property. This reason is hereinafter referred to as
"Topographical I"

ADD SECTION 1613.8 TO SECTION 1613:
1613.8 ASCE (AMERICAN SOCIETY OF CIVIL ENGINEERS) 7, Section 12.8.1.1.
Modify ASCE 7, Section 12.8.1.1 by amending Equation 12.8-5 as follows:
Cs = 0.044 SDS I ~ 0.01
(Eq. 12.8-5)
REASONS FOR AMENDMENT:
Re-adoption from previous code.
ADD SECTION 1613.9 TO CBC SECTION 1613:
1613.9 ASCE 7, Section 12.8.7. Amend Equation 12.8-16 as follows:
() = PJ~ I
V h C
x -,x d
(Eq.12.8-16)
REASONS FOR AMENDMENT:
The importance factor, I, was omitted from Equation 12.8-16 by mistake while
transcribing it from the 2003 NEHRP (National Earthquake Hazards Reduction
Program) Recommended Provisions (FEMA (Federal Emergencv Management Agencv)
450) Equation 5.2-16. For buildings with importance factor, I, higher than 1.0, the
stability coefficient should include the importance factor. The proposed modification is
consistent with the provisions adopted by DSA-SS (Department of State Architects
Structural Safety) and OSHPD (Office of Statewide Health Planninf! and Development)
as reflected in Section 1615.10.7 of the 2010 California Building Code. It is also
consistent with ASCE (American Society of Civil Engineers) 7-10 Equation 12.8-16 that
will be adopted in the next code cycle. TUCC (Tri-Chapter Uniform Committee) had
supported the proposed modification during the 2007 code adoption process. This
proposed amendment is a continuation of an amendment adopted during the previous
code adoption cycle.
AMEND - Amendment Modifications to CBC Section 1704.4- Special Inspection
Amend Section 1704.4 to read:
1704.4 Concrete Construction. The special inspections and verifications for
concrete construction shall be as required by this section and Table 1704.4.
EXCEPTIONS: Special inspection shall not be required for:
1. Isolated spread concrete footings of buildings three stories or less in height
above the grade plane that are fully supported on earth or rock, where the
structural design of the footing is based on a specified compressive strength. fc.
no greater than 2.500 pounds per square inch (psi) (J 7.2 Mpa).
ORDINANCE NO. 2010-17
14
2. Continuous concrete footings supporting walls of buildings three stories or less
above grade plane that are fully supported on earth or rock where:
2.1. The footings support walls oflight-frame construction;
2.2. The footings are designed in accordance with Table 1809.7; or
2.3. The structural design of the footing is based on a specified
compressive strength, fc, no greater than 2,500 pounds per square inch
(psi) (17.2 Mpa), regardless of the compressive strength specified in the
construction documents or used in the footing construction.
3. Nonstructural concrete slabs supported directly on the ground, including
prestressed slabs on grade, where the effective prestress in the concrete is less
than 150 psi (1.03 Mpa).
4. Concrete foundation walls constructed in accordance with Table 1807.1.6.2.
5. Concrete patios, driveways and sidewalks, on grade.
REASON FOR AMENDMENT:
Results from studies after the 1994 Northridge earthquake indicated that a lot of the
damage were attributed to lack of quality control during construction. The proposed
amendment improves quality control during construction and therefore needs to be
incorporated into the Code.
Revise CBC Section 1704.4 exception No.1 to allow special inspection not to be
required for isolated spread footing where the structural design of the footing is based on
a specified compressive strength, f c, no greater than 2,500 psi.
This proposed amendment is a continuation of an amendment adopted during the
previous code adoption cycle.
AMEND SECTION 1807.2 AS FOLLOWS:1807.2 Retaining walls. Retaining walls
shall be designed in accordance with Section 1807.2.1 through 1807.2.4

1807.2.4 Retaining walls shall be constructed of concrete or masonry and be
designed by a California State licensed engineer (Civil or Structural Engineer).
REASONS FOR AMENDMENT:
1. Geological I.
2. This existing amendment continues to be required by local conditions.

DELETE SECTION 2505 COMPLETELY.
ORDINANCE NO. 2010-17
19
REASONS FOR AMENDMENT:
Survey of structural failures after the Loma Prieta earthquake of 1989 showed the
gypsum board, plaster and stucco finishes used for lateral force resistance preformed
poorly or failed completely. Further, once used to resist lateral forces, it is nearly
impossible without completely replacing the material to achieve the initial design load
resistance in these materials. To minimize the potential for increased fire-life safety
problems associated with such seismic failures, this proposed modification increases the
minimum acceptable shear resisting elements to be used for lateral designs and
conventionally braced structures. Further, this continues a trend in and amongst local Bay
Area jurisdictions that has been historically supported by the engineering community.
